Mexico says it has arrested a suspected drug trafficking kingpin who also is wanted in the United States.

Mexican federal police Wednesday said they detained Luis Rodriguez Olivera, known as “El Guero,” at Mexico City's international airport the day before. The U.S. had offered a reward of $5 million for information leading to his capture.

Rodriguez Olivera is accused of trafficking massive quantities of cocaine into the U.S. between 1996 and 2008. He also has been charged with money laundering.

The arrest is Mexico's second major blow against drug trafficking cartels in two weeks.

Last week, Mexican authorities captured a suspected lieutenant to the elusive leader of the powerful Sinaloa drug cartel.

Felipe Cabrera, also known as “The Engineer,” was said to be a top aide to the head of the Sinaloa cartel, Joaquin “El Chapo” Guzman. Officials said Cabrera rose through the ranks by using violence against his rivals.

Mexican President Felipe Calderon has deployed thousands of troops across Mexico to fight the country's drug cartels. The spiraling violence has left at least 50,000 people dead.
